Question

自从迁移到Spring 4以来，我遇到了一个奇怪的问题。 Application使用dwr进行Ajax调用。 Ajax帮助程序调用该服务。

错误是

org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.

AjaxSiteDnsHelper.java

public void removeSiteDnsEntry(Long siteDnsEntryId) throws ItemNotFoundException, ServiceException {
    final Site site = getSite();
    site.setModifiedBy(getUser());
    for (SiteDns siteDns : site.getSiteDnsEntries()) {
        if (siteDns.getId().equals(siteDnsEntryId)) {
            site.getSiteDnsEntries().remove(siteDns);
            break;
        }
    }
    siteServices.saveOrUpdateSite(site);
}


Transactional(readOnly = true)
public class SiteServices extends NavigationServices implements ISiteServices {


//some code
@Override
@Transactional(readOnly = false, propagation = Propagation.REQUIRED)
public void saveOrUpdateSite(final Site site) throws ServiceException {

    siteDAO.saveOrUpdate(site);

    if (site.getExternalFeedUser() == null) {
        site.setExternalFeedUser(createDefaultSiteUser(site));
    } else {
        site.getExternalFeedUser().setUsername("DOD " + URLMappingUtils.generateSiteUgcEditorUsername(site));
    }

    LOG.info("Setting default user to '" + site.getExternalFeedUser().getUsername() + "'");
    userDAO.saveOrUpdate(site.getExternalFeedUser());
}

web.xml已

hibernateOSIV org.springframework.orm.hibernate3.support.OpenSessionInViewFilter sessionFactoryBeanName SessionFactory的

persistence-context.xml有

<bean id="hibernateInterceptor" class="org.springframework.orm.hibernate3.HibernateInterceptor">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

transactional-context.xml有

  <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" >
    <property name="sessionFactory" ref="sessionFactory"/>
  </bean>

  <tx:annotation-driven/>

有人建议我在创建代理时需要重构代码以删除类的层次结构。我把调试放在OpenSessionInViewFilter.setFlushMode上。但它似乎没有被调用，并且正在使用MANUAL的默认flushmode。

由于flushmode是MANUAL，因此事务提交失败
